66 results about "Solvent dye" patented technology

A solvent dye is a dye soluble in organic solvents. It is usually used as a solution in an organic solvent. Solvent dyes are used to color organic solvents, hydrocarbon fuels, waxes, lubricants, plastics, and other hydrocarbon-based nonpolar materials. Fuel dyes are one use of solvent dyes. Their molecules are typically nonpolar or little polar, and they do not undergo ionization. They are insoluble in water. They form a colloidal solution in solvents. They have poor (basic dyes) to good (metal complex based) light fastness.

Flat polyester fiber master batch applicable to spun dyeing process and preparation method of master batch

InactiveCN106700439AMeet post-processing color fastness requirementsMonocomponent polyesters artificial filamentArtifical filament manufacturePolyesterFiber
The invention provides flat polyester fiber master batch applicable to a spun dyeing process. The flat polyester fiber master batch comprises the following components in parts by weight: 0-30 parts of PBT (polybutylece terephthalate), 40-80 parts of bottle-grade PET (polyethylene terephthalate), 0-30 parts of a coloring agent, 0-5 parts of an aid and 0.1-0.6 part of calcium carbonate, wherein the coloring agent is selected from one or more of a condensed azo pigment, a phthalocyanine pigment, an aminoketone red solvent dye, a quinophthalone yellow solvent dye, a perylene series green solvent dye, an anthraquinone blue solvent dye, an anthraquinone purple solvent dye and an inorganic pigment carbon black; the aid comprises an organic silane high molecular weight dispersing agent. The invention further provides a preparation method of the flat polyester fiber master batch. The flat polyester fiber master batch provided by the invention is applicable to a spun dyeing process, the problems that fiber has very large deformation when being produced and a cross section of the fiber cannot be well maintained can be solved, meanwhile situations of fiber deviation, breakage and fiber burring can be solved, and moreover aftertreatment color fastness requirements can be met.

Laser transfer coating for pre-coloring and preparation method thereof

The invention relates to a laser transfer coating for pre-coloring, which is prepared from the following components: 0-12% of polyamide resin, 0-10% of polyester resin, 0-5% of vinyl chloride-vinyl acetate resin, 2-30% of polyacrylate resin, 0-4% of amino resin, 0-9% of nitro-cotton resin, 0.2-0.6% of cross-linking agent, 0.4-1% of dispersing agent, 1.2-1.5% of wetting agent, 68-84% of solvent and 0.8-1% of dye. The preparation method of a water transfer printing laser coating comprises the following steps: preparing raw materials; adding the solvent into a reaction kettle, stirring, and heating; sequentially adding the resin, and stirring at high speed until the resin is completely dissolved; sequentially adding the cross-linking agent, the dispersing agent and the wetting agent slowly, and stirring at medium speed until the cross-linking agent, the dispersing agent and the wetting agent are dispersed uniformly; adding the dye slowly, and stirring at high speed until the dye is dispersed uniformly to obtain a solution of the laser transfer coating for pre-coloring; sampling, and measuring solid content and viscosity; and stirring at medium speed, cooling, and filtering to obtain the laser transfer coating for pre-coloring. The laser transfer coating for pre-coloring and the preparation method thereof can be applied to the pre-coloring process of laser transfer products.

The invention discloses a preparation method of modified time-resolved fluorescent microspheres. The preparation method comprises the following steps: (1) adding ultrapure water into a reaction kettle, introducing nitrogen, stirring while heating, adding rectified polystyrene, mixing and heating, then adding potassium persulfate, and fully reacting to obtain white latex spheres; and (2) weighing asolvent dye, 2-thiophene formyl trifluoroacetone, phenanthroline hydrochloride, europium chloride and an electron mediator, dissolving the solvent dye, the 2-thiophene formyl trifluoroacetone, the phenanthroline hydrochloride, the europium chloride and the electron mediator in petroleum ether to generate a mixture, slowly adding the mixture into a white latex microsphere solution prepared in step(1), uniformly stirring to obtain dyeing time-resolved fluorescent microspheres, heating to completely volatilize petroleum ether, and repeatedly centrifugally washing the synthesized microspheres tocompletely wash away redundant dyes in the solution in order to obtain the microspheres with bright colors and without influencing the time-resolved fluorescence of the microspheres. A user does notneed to read numerical values through an instrument when using the microspheres, and the reason of abnormality can be visually found out for an abnormal test strip.
